Support multi-field JOIN syntax in JPQL FROM clause

While we currently allow joining across a single field in the FROM clause, we could also support joining across multiple fields. For example the following is supported
SELECT Object(G) FROM UserGroup G INNER JOIN G.members M

and the following is not supported
SELECT Object(G) FROM UserGroup G INNER JOIN G.members.details D
